Abstract

Elément allongé formant une tige de soutien spinal à implanter en position adjacente à la colonne vertébrale, comprenant un ou des volets axiaux couvrant des niveaux respectifs de la colonne vertébrale et favorisant ainsi un soutien/une stabilisation efficace de la colonne. Le type de volet considéré présente une géométrie hélicoïdale double et a un profil en forme de tige de diamètre similaire aux tiges de soutien spinal classiques que l'on utilise en fusion spinale lombaire, aux fins d'application sur plusieurs niveaux de la colonne et à points de fixation réglable multiples pour des dispositifs de fixation spinale correspondants, du type vis de pédicule, permettant de s'adapter à différentes anatomies.
